I would say Simon found that on the whois info as I also see it there.
The very first whois record is inserted on 2003-01-19 though… There is nothing before that…
First registrar history was 2002-11-25
Whois usually only records stuff intermittently too.. so that first whois record may have occurred on the first change from registration or something like that.
So Simon I would say the whois 2007 date is just showing the last time it was renewed…
